Original reference address

General comparison: On the left is the Jaeger-LeCoultre Master series 1378420 watch (Joker), on the right is the meticulous workmanship of AZ. The general appearance of the two is quite similar, there is no significant difference. The original uses a crocodile leather strap; AZ preferred Italian calfskin.

Case and Body Workmanship

Watch body comparison: The overall similarity of the cases is very high. At different angles and lights, the mood of the two is exactly the same; The dial layout is also exactly similar, there is no difference in the overall layout and shape. AZ has perfectly captured the spirit of the original.

Dial and Hand Details

Dial detail comparison: The clarity of the sapphire glass is excellent, the print of the JL logo is finely processed. AZ has also brought back the power reserve indicator of the original (the small dial at 10 o'clock is the power reserve indicator), with the seconds function and first-class workmanship, the shape and size are extremely close to the original (the small seconds dial at 6 o'clock is); The font and position of the date display are also very appropriate (it is the date display at 2 o'clock).

Glass and Sapphire Crystal

Case comparison: The proportions of the AZ case are very good, the sapphire glass is extremely compatible with the case, and the lugs are not much different from the original; The case lines are fluent and the workmanship is high quality.

Crown and thickness comparison: AZ kept the thickness within the smallest margin of error; The case dimensions are almost indistinguishable to the naked eye. The JL logo on the crown is distinct and dimensional, the shape and size are the same; The non-slip texture is round and machined on site.

Movement and Caliber Performance

Movement comparison: AZ did independent development based on the original factory's Cal.938 movement; It has implemented the bidirectional installation function of the original movement, restored the feel and sound of the original, and made the movement performance more stable by using the same KIF shock absorber as the original. The balance wheel position of the mechanism is also the same as the original; It is not distinguishable at first glance. The factory is attentive, and we are at peace.

Case back comparison: AZ also used sapphire glass on the case back; It has an extremely clear, abrasion and scratch resistant appearance. The number engravings on the case back circle are exactly true to the original; Even the smallest details are at a high standard of workmanship.

Strap, Buckle and Comfort

Strap comparison: The AZ buckle is perfectly made inside and out, its proportions are balanced, and the engraving on it is clear and smooth. JL's classic butterfly buckle is produced with fine workmanship and the polishing is also top-notch; The logo design is the same as the original, very classic and characterful. Italian calfskin is very comfortable to use with its soft texture.

AZ has put a lot of effort into the movement and crafted the Jaeger-LeCoultre Master series Q1378420 Joker watch with great sincerity, inside and out.

General Evaluation and Conclusion

Summary: Overall a really good and very careful job. YL and AZ are currently using the same mechanism; Other factories will probably supply and produce it in the future. Finally, let me say a word about the simple mistake in YL Factory's Joker model: the engraving of the mechanism model was really sloppy. If you like it, you can buy it with peace of mind, there is no problem.
